This is not a library, so there's no reason for them to be `pub`.

error: could not compile `std` (test "create_dir_all_bare") due to 2 previous errors
This happens because Cargo passes `--extern 'priv:std=...` when
compiling the test crate.
I'm not sure if these warnings are desirable or not. They seem correct
in a very pedantic way (the dependency on `std` is not marked public,
since it's implicit), but also pointless (the test crate is not an API,
so who cares what it does).
This switches to using a `Cell` for single-threaded rustc.

Compiletest was switched to querying all targets using `--print=all-target-specs-json` and `--print=target-spec-json` in rust-lang#108905. This unintentionally prevented codegen flags like `-Cpanic` from being reflected in the current target configuration. This change gets the current compiletest target config using `--print=cfg` like it was previously while still using the faster prints for getting information on all other targets. Fixes rust-lang#110850.

Rework handling of recursive panics
This PR makes 2 changes to how recursive panics works (a panic while handling a panic).
1. The panic count is no longer used to determine whether to force an immediate abort. This allows code like the following to work without aborting the process immediately:
```rust
struct Double;
impl Drop for Double {
fn drop(&mut self) {
// 2 panics are active at once, but this is fine since it is caught.
std::panic::catch_unwind(|| panic!("twice"));
}
}
let _d = Double;
panic!("once");
```
Rustc already generates appropriate code so that any exceptions escaping out of a `Drop` called in the unwind path will immediately abort the process.
2. Any panics while the panic hook is executing will force an immediate abort. This is necessary to avoid potential deadlocks like rust-lang#110771 where a panic happens while holding the backtrace lock. We don't even try to print the panic message in this case since the panic may have been caused by `Display` impls.
Fixes rust-lang#110771

…error, r=dtolnay Remove unnecessary Send bound Hi, While working on a [PR on Tokio](tokio-rs/tokio#5666), I took inspiration from the std channel mpsc and stumbled on a `Send` bound for a `Error` impl. Tokio's maintainer `@Darksonn` pointed out to me that `Error` used to required the `Send` bound long time ago (here rust-lang#23541). In the meantime, the `Send` bound `Error` got removed (see rust-lang#21312 and rust-lang#23799). So here a PR to removed this bound for `SendError<T>`, `TrySendError<T>` and `SendTimeoutError<T>`.
…target, r=compiler-errors Get current target config from` --print=cfg` Compiletest was switched to querying all targets using `--print=all-target-specs-json` and `--print=target-spec-json` in rust-lang#108905. This unintentionally prevented codegen flags like `-Cpanic` from being reflected in the current target configuration. This change gets the current compiletest target config using `--print=cfg` like it was previously while still using the faster prints for getting information on all other targets. Fixes rust-lang#110850. `@jyn514` might be interested in reviewing since they commented on the issue. cc `@tmandry` since this issue is affecting Fuchsia.
Document that `missing_copy_implementations` and `missing_debug_implementations` only apply to public items. I encountered rust-lang#111359 (fixed) and noticed that the documentation didn't say that it was _intended_ that `missing_debug_implementations` only applies to public items. This PR fixes that, and makes the same wording change to `missing_copy_implementations` which has the same condition. I chose the words to also be similar to `missing_docs` which already had such a remark.
…rrors fixup version placeholder for `cfi_encoding` feature Mentioned rust-lang#105452 (comment)
Add clubby789 to the bootstrap review rotation r? `@clubby789` - thank you for volunteering! I have been meaning for a very long time now to write up how to do reviews, but I haven't gotten around to it yet :( here is a short summary: 1. If you're not sure what the changes does or if it's ok, always feel free to ping someone else on the team, especially in the first few weeks. You can use `r? bootstrap` to get triagebot to assign someone else. 2. Bootstrap unfortunately has very few tests. Things that touch CLI or toml parsing should likely have a test in `src/bootstrap/config/tests.rs`; things that touch "core" build logic should have a test in `builder/tests.rs`, anything else kinda just slips in :( see rust-lang#102563 for ideas on how to improve the situation here. 3. "Major" changes should be documented in `src/bootstrap/CHANGELOG.md`. "Major" is up to you, but if it breaks a config option or otherwise is likely to break *someone's* build, it's probably major. If it breaks nearly *everyone*'s build, it should also update `VERSION` in `lib.rs`; this should be very rare. Please also ping me or Mark-Simulacrum for major changes (I might set up a triagebot ping for this so you don't have to remember). 4. Once you've approved the PR, tell bors it's ok - you've been contributing for a while so you know how bors works, but here's a cheatsheet just in case: https://bors.rust-lang.org Documentation about how to use bootstrap lives at https://rustc-dev-guide.rust-lang.org/building/bootstrapping.html; internal docs live in `src/bootstrap/README.md`. The latter unfortunately is not very complete.
